What to do if you might be infected
The Centers for Disease Control and Prevention reports that 90 percent of unvaccinated people exposed to the measles virus come down with the disease. The virus lives in the nose and throat mucus of an infected person, and can survive for up to two hours in an airspace where the infected person coughed or sneezed.
Health officials are urging anyone who has been exposed at an identified location and believes they have symptoms of measles to call their health care provider prior to visiting the medical office to make a plan that avoids exposing others in the waiting room.
If you are unsure of your family’s immunization status, you can view, download and print your family’s immunization information online at wa.MyIR.net or request a copy of your immunization record from the Washington State Department of Health.

Measles symptoms begin with a high fever, cough, runny nose and red eyes, followed by a rash that usually begins at the head and spreads to the rest of the body. A person can spread the virus before they show symptoms.
People are contagious with measles for up to four days before and up to four days after the rash appears. After someone is exposed to measles, illness develops in about one to three weeks.
